5 useful Improvement in WVindow-Blinds, of

whichthe following is a specification.

My invention relates to an improvement in the mechanism for opcningand closing the slats of blinds and in providing a device for IO locking or holding them securely either open or shut. I attain these objects by means of the mechanism shown in the accompanying drawings, in which- Figure 1 is a plan View of the inside of the [5 blind. Fig. 2 is a cross-section on the line P P of Fig. 1. Fig. 3 is an outline view of one of the fasteners. Fig. 4 is an end view of one of the slats, showing the manner of attaching the fasteners.

20 Similar lettersrefer to similarparts throughout the several views.

A is the frame ofjhe blind,-in which the slats B are pivoted in the usual manner.

0 is the rod by which the slats are operated. I prefer to construct the slats of the shape shown more clearly in Fig. 4, each slat having a bead, e, on its upper edge, and a recess, a, on its lower opposite edge, so that the slats, when closed, fit closely together, so as to en-' 30 tirely exclude light, dust, rain, andsnow.

The fasteners D,which serve to connect each slat with the operating-rod C, are of the shape shown in Fig. 3. The parts a and b are bent at right angles to each other along the dotted The fasteners are attached to each slat, as clearly shown in Fig. 3, by means of staples 0, which are'forced or driven into the slat through holes 8 s in the part b of the fastener, being clinched on the Opposite side, in

0 Order to hold the fastener and slat securely and firmly together. Each slat is secured to the operating-rod by means ofpins f passing through a hole, (1, in the end of the arm a of the fastener.

It is not essential to my invention that slats or fasteners of the shape or kind specified be used, as it can be applied to any blind having pivoted slats and an operating-rod for opening or closing them simultaneously.

The mechanism for opening and closing the L slats and locking them in either position consists of the circular disk H, which is attached by a screw at its center to the bottom rail of the blind. Ashort curved link, I, ofth'e shape shown in Fig. 1, extends from the lower end of the operating-rod O to a pin, '5, near the rim of the disk H. A suitably-shaped recess in the raised hub of the disk H (I prefer to make it square, as shown in the drawings) has a key, J, fittedto it, by means of which the disk can be rotated. The key J may be made of sufficient length to pass through a hole in the bot tom rail of the lower sash of the window, so

that the blind-slats can be opened and shut Without raising the window. A screw or pin, 9, driven into the bottom rail of the blind and projecting out through the circular slot It serves as a stop to prevent the disk H from being rotated farther than 'is necessary for operating the blind-slats.

In the drawings the slats are represented as closed. To open them the key J is placed in the aperture in the center of the disk H Patent, is

The mechanism for opening, closing, and locking blind-slats, consisting of the disk H, with curved slot h, pin '11, and link I, combined with a slat-operating rod, 0, substantially as and for the purpose specified.
